Project description:The Yeonsan Ogye (Ogye) is the rare black chicken breed domesticated in Korean peninsula, which has been noted for entire black color upon its appearances including feather, skin, comb, eyes, shank, claws and internal organs. In this study, whole genome, transcriptome and epigenome sequencings of Ogye were performed using high-throughput NGS sequencing platforms. We have produced Illumina short-reads (Paired-End, Mate-Pair and FOSMID) and PacBio long-reads for whole genome sequencing (WGS), 1.4 billion reads for RNA-seq, and 123 million reads for RRBS (reduced representation bisulfite sequencing) data. Using WGS data, Ogye genome has been assembled, and coding/non-coding transcriptome maps were constructed on Ogye genome given largescale sequencing data. We have predicted 17,472 (3,550 newly annotated and 13,922 known) protein-coding transcripts, and 9,443 (6,689 novel and 2,754 known) long non-coding RNAs (lncRNAs).

Project description:We exploited the methylation genome-scale screening RRBS to correlate the RNA species physically associated with DNMT1 and proximal to the annotated genes to the methylation status of the corresponding loci. Out of 15275 non ambiguous gene loci identified by DNMT1 RIP-Seq, 9436 loci were covered by RRBS. These 9436 loci were clustered according to the fold of specific DNMT1 library peaks enrichment (defined as the ratio of the sum of the area under the curve of specific DNMT1 library peaks covering the gene loci). Genes were then stratified by the expression profile ultimately leading to the epitranscriptome map, a comprehensive map cross-referencing DNMT1-interacting transcripts to (i) DNA methylation and (ii) gene expression profile.
